find the Sony 10-18mm and Sony Zeiss 16-70mm remarkably similar, the
PZ 16-50 notably softer and the acuity on the 24-70 FE highest. It
appears Sony took the PZ strategy with the 24-70 FE, making it wider
than the marked focal length and then cropping to alleviate the heavy
vignetting. I'd like to continue with the slides, but WowSlider is not
keen on allowing more than one slideshow on a page due to errors in
their coding. So I'm going to keep it simple.
